Touareg :: Mechanical Sound While Stopping / Accelerating - A/C Blowing Hot Air
Apr 29, 2009
I have the 2 zone auto climate control system.
1. When I come to a stop, there is a mechanical sound coming from behind the central vents as though a flap is trying to move. After I accelerate, I hear it for a a little longer but then it eventually goes away but returns again when I stop. I usually leave the setting in auto but even manually manipulating the controls doesn't seem to get rid the noise.
2. For a high end system with automatic climate control, it is a pretty crappy system. Main gripe is in the morning, let's suppose it's 12 deg C / 55 deg F outside and the system is set for 20 deg C / 70 deg F, it insists on blowing hot air!!! It's as though it's sensing the outside temp or ovber compensating. Eventually after 10 - 15 minutes everything settles down.

I own a 2007 Honda Civic. For the last several months, the car starts making a strange mechanical whining sound when turned on. The sound grows louder when accelerating or going in higher rpms. It also seems to get a little quieter when I turn on the air conditioning. But the soubd never goes away. Car otherwise runs perfectly fine and never fails to start. Took it to two different honda dealerships to have it looked at. One said it had something to do with the a/c, the other said the alternator might be the alternator. I tested the alternator with a voltmeter and it seems to be working just fine. However, when you open the hood, the sound seems to be coming from the alternator area.

I have been getting a loud, high-pitched mechanical-sounding noise coming from the middle of the dash, near the CD player. It lasts only a few seconds, but it scares the sh!t out of me every time! It happens out of the blue after I've been driving for a few minutes about every 3 weeks or so. The sound is almost impossible to describe...but if you've had it happen you probably know exactly what I'm talking about. It happened today while I was listening to a CD, so I can't imagine it's the player that's doing it. Non-Nav/Air V8

Last night our prius started making a mechanical sound when we shift into forward or reverse.

I have a 2-door gti that is relatively brand new. One thing I've noticed though is that the driver-side has a mechanical squeak/straining sound when I lean with some force in to the right side of the chair. I figured this was not normal, what it might be?

This is what is happening:
1. When you start driving the car it accelerates fine until it gets to second gear where it keeps accelerating, then you feel a jolt, the odometer jumps 1-2 notches, and it switches into third.
2. When stopping it downshifts fine until second gear getting ready to switch into first to come to a complete stop and again it "jolts"
3. (Sometimes happens) When driving ~25 mph or ~40 mph while continuously accelerating you let-off the gas and then reapply, it stops accelerating and kind of "sputters" and can not accelerate anymore, I have to stop put it in Park and then again put it in Drive and only after that it works fine.
I have taken it to the VW Service and the mechanic could not replicate what I said was happening so I drove with him in the car and replicated the first two steps 3 out of 6 times. He told me that they checked the codes and could not find anything malfunctioning. I told him that clearly something was wrong with the transmission and I wanted something to be done. He agreed that he also felt what I was talking about but it was not enough to come to a conclusion to what was wrong. I mentioned that I wanted this to be written down in the service report, because if something happens they will be aware.
The problem now is that the "jolting" and the stalling-out has gotten worse since the visit to the service 1 month ago. What might be happening and what I need them to repair/change on my car. I am planning on making a visit sometime this week. The first two steps happen when the car is cold or when I switch over form Tip-Tronic to automatic. But that is not always the case.

I had heard clunking when hard accelerating or hard stopping my 2003 Explorer, also heard it from Park to Reverse/Drive. I suspected u-joints, was correct, those were replaced.
After I received my car back I noticed the clunk was louder when hard accelerating or hard stopping; again from Park to Reverse/Drive. I suspected rear differential. I called my mechanic who said they noticed some play in the rear end - a little loose, that the noise would be noticeable...but that if it were him he wouldn't worry about it. He said the drive shaft was tight, that I wasn't in danger of it falling out, etc.
These are the only symptoms I have that something is wrong with the SUV. Just that clunk. If I come off slow from a stop and not hit the gas, there is no clunk. If I do not hard stop, again I can avoid the clunk. The vehicle does not vibrate or make noise on the freeway, shifts well between gears.
I was going to have my mechanic open the rear end up and see what needed to be replaced when the cold weather brakes. In the meantime, is there anything I need to be keeping an eye on, or something else I should check? My mechanic said the checked it over and couldn't find any other problems. I just want to be prepared for expenses.
It's a 2W, not 4WD. I had all the fluids done, a drain and refill on rear. Not sure if that's important to know or not.

I have a 2002 Civic LX. A/C worked until a few months ago. It would stay on for about ten minutes and then stopping blowing cold air; it would come back on and then go off again at it's own whim. Bought it to local Goodyear - told them the problem - they charged me about $130 to evacuate and recharge, looked for leafs but told me they saw no problems with the A/C, the condenser was fine, etc. A few days later, same problems started. Runs great for about ten minutes and then does its own thing.

I've had 2013 Elantra for a month. Love it, but a week ago, the driver's seat started squeaking when stopping, accelerating, and going around curves. Crazy making! I took the car in today. Svc mgr said its a weight issue. The two driver/owners weigh 150 and 160 lbs! Exactly, he said. Apparently, we do not weigh enough to prevent squeak. The only fix would be to replace the seat and there's no guarantee it would work. Also must be approved by regional svc mgr so have to go back in a.m. Told them similar issues posted online (Genesis and Sonata) and was easily resolved lubricant issue. They could at least try what appears to work. No going.
Have other Elantra owners experienced this squeaking? If Hyundai knows this is a recurring issue with their products, at what point do they make engineering changes to resolve the issue? Don't want to, but I am rapidly losing my love for the car as it sounds like a cheap tin can when it squeaks.

Well, my saga continues on my intermittent AC problem on my 99 f350 v10. As before, the AC blows cold but mysteriously stops working on occasion when climbing a grade or stopping at a light in warm weather. I bought a gage kit and runs ~ 45/250psi on the low/high gauges. Clutch is stopping and the metal tube from the accumulator tank runs warm when this occurs.
Seems like the problem occurs when the under hood temp reaches a certain level. Thought it might have been one of the switches but the pressure seems to be OK when these problems are occurring. What/how to check to find the problem? some of my thoughts are:
1. Wire a light in the clutch engagement circuit to see if the problem is in the compressor clutch coil not working when powered up or some heat related failure of the wiring continuity.
2. Check the Hi and low pressure switches for continuity when this is happening. to do this I need to know a few things- location of the high pressure switch low press in on the accumulator) and whether the switch should be open or closed in normal operation. Also can the switches be replaced without losing the charge in the system?

I have about 1300 mi on my V6. And for the last 600 or so miles the brakes squeak loudly when stopping at a red light.

I am trying to get a sense on how prevalent this issue is. Getting brake noise when stopping? It is progressively getting worse, and my Treg has been in 4 times for that issue alone. My dealership, i think has sort of given up. They tried "grinding" the edges down as suggested by VWoA, no go...

i have with my Treg. Occasionally, like once every two weeks, when I am slowing down to almost a standstill, i suddenly hear a loudish grinding noise that seems like it was triggered electronically. I seem to think it happens when the auto box is shifting from 2nd to 1st before the car comes to a standstill, but not every time. Obviously when I took it to the dealer it did not happen!

I just recently purchased an 05 Touareg V6 and I am a little concerned regarding the acceleration I am getting like after stopping at a light or trying to get on the highway. It seems that it takes this vehicle about 5-10 seconds to realize that it needs to get moving. However, after it does realize what it needs to do, the acceleration is fine. I was told different things such as it could be the turbo system and one thing I find very hard to believe that this is a characteristic of all VW's. I like my VW and don't want to get rid of it but would prefer better acceleration

The brakes in my new '05 Treg are really, really touchy, especially when going super slowly (1 mph or less), or stopping completely. I find it almost impossible to bring the entire vehicle to a complete stop without the vehicle "jerking" backwards - if you know what I mean. It's almost like the brakes were being operated by an on/off switch. I got the "nothing can be done, that's how they all are" speech today from my dealer. Any solutions? Different brake pads, maybe?

I purchased front brakes and rotors from O'Reilly Auto Parts, for my 2006 Porsche Cayenne. The brakes were grinding while stopping the car, so I went to O'Reilly and talked to them about the problem. They suggested that I get different pads. I ordered different brake pads, installed them and returned the others. Now the second round of pads are making that grinding sound again while stopping the car. I checked the rotors and they seem to be fine.Is there special pads that will not make that grinding sound? If so, where is a good place to get them from?

I am having an interesting sound coming from my rear brakes when I stop from reversing, for example, when I'm pulling out the drive way or a parking space. It kind of sounds like a loud "hum" that lasts a spit second, until the car actually stops. I changed the rear brakes and rotors about 1500 miles ago.

I recently bought a used 2003 jetta wagon with 159k. Is it normal to feel and hear a growling sound when the air cond is running and you stop for a red light. It's a 2.0 automatic jetta wagon. I never had a 4 cylinder automatic car and this is my first VW.

I have a 1998 Ford Ranger, 3.0 4X4. Purchased in early 2002 with a clunking problem which has not gotten worse or better. When I take off it is a heavy double 'clunking' like something shifting and the settling. I have had 4 mechanics look at it, have changed the front u joint and have had the motor and transmission mounts checked but the mounts are OK. Can't figure this out. I talked to a person at a local car parts store and he mentioned that it could involve the 'yoke' and that it just might need to be greased but he was just guessing.

I am hearing a water flow sound under the right side of the dash when I turn corners or stop. It started when the radiator cracked. I have replaced the radiator and water pump. I have filled the radiator with the front of the SUV up and the engine running. Also tried jacking the rear of the SUV up. I have flushed the heater core. And re connected the hoses bleed air at the top of the hoses from the heater core, the return from the water pump to the radiator, and at the radiator to the water pump. Yesterday I pulled the dash out and found the heater core to be more center of the dash behind the climate control. The sound seems to be coming from more right behind the glove box. Any suggestions before I reassemble the dash. I have removed and cleaned the lower half of the ac coil/condenser box. There was no fluid in it and the drain line was not plugged.

I'm getting a readlly hard thump or slam from my transmission when accelerating. It only seems to happen when it shifts from 5 down to 4. This is usually when rounding an exit ramp, then excellerating back onto a highway. It's really bad and enough to make me nearly wet myself when it happens. It feels like the transmission is going to snap in half or something.
